"arm integral with saidfbracket '1.

so that the tractor may be stopped on any To this end the invention comprises a bracket carrying a leverv with an operating rod pivotallyjsecured thereto and adapted I to engage thetractor clutch pedal, and provided with means for holding the lever 1n position to maintain the clutch in a released position. The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawing, in which Figure 1 is a side view of a fragment. of a tractor showing the improved clutch control mechanism in place thereon, and

Fi ure 2 a rear View, the clutch pedal being s own in transverse section. In the drawing similar reference characters will be used to designate corresponding parts in both of the views.

A tractor is shown fraginentally at A", and has a bracket 1 secured to the frame thereof by means of bolts or other suitable fastenings 2 secured to a downwardly extend Ii rlig 1e bracket 1 is also provided with a ratchet face 4. Fulcrumed on the bracketl is a lever 5, 6 indicating the fulcrum of said lever, and 7 is a thumb latch mounted on the lever and actuated by an L-shaped rod 3 8. having its angular end 9 conveniently locatedunder the angular end 10 of the lever.. Lever 5 has an offset'portion 11 to which is pivotally secured a rod 12 extending downwardly and having adjacent to its lower end another. rod- 13 secured thereto through an ofiseterid 1 th The construction of the lower end of the rod 12 with the rod 13 provides a forked structure, the two fingers of the fork formed by the lower end of the rod '12 andthe rod 13 engaging on a opposite sides of the clutch pedal B of-the tractor A. 1

"Rods-12 and 13 are provided with series of openings 15 to'sele ctively receive a pin 16 and engaging the pedal B.. It will beapparent that with the control mechanism above described installed be operated to release the clutch by actuat ing the lever 5, the thumb latch 7 holding the lever in adjusted position, and with'the clutch mechanism installed the engine of the tractor maybe left running and the tractor in gear to run the driving wheel on sloping A. clutch control mechanism for tractors, comprising a bracket, a downwardly extend: ing arm thereon adapted to be secured to the 16, and 17 is a rollermounted on said pin clutch onthe tractor shown the clutch pedal B may i frame of a tractor, a segmental ratchet on said bracket, a lever fulcrumed on I said bracket, a thumb latch carried by said lever and adapted to engage said ratchet, a rod pivotally secured to said lever, another rod having an offset end secured to the first mentioned rod and forming a forked member to enclose the clutch pedal of the tractor between its fingers, and a pin bridging the space between said rods and adapted to engage .the pedal, said rods being provided with a plurality of oppositely disposed open ings for adjusting the position of said pin.

In testimony whereof I affix my signature.
